Abstract

Eradicating rice pests in South Kualuh is difficult to do optimally, because most farmers do not understand the types of pests that attack their rice plants. The objective of this study was to obtain information about the type of pest insects in rice plants and to find out the diversity index of insect pests in rice plants. This research was conducted using trap method and collection of insects was done using a insect net. Observation data was analised using Shanon Wiener (H) diversity / diversity index. The result showed 13 types of pest insects which belongs to 10 families. That is Tettigonia sp.(Linnaeus, 1758), Sogatella furcifera (Horváth, 1899), Nephotettix virescens (Distant, 1908), Cofana spectra (Distant, 1908), Atractomorpha crenulata (Fabricius, 1793), Erotides sp.(Laporte, 1836), Leptocorisa acuta (Thunberg, 1783), Aulacophora indica (Gmelin, 1790), Chrysochus cobaltinus (LeConte, 1857), Silba capsicarum (McAlpine, 1956), Hercostomus germanus (Wiedemann, 1817), Cnaphalocrosis medinalis (Guenée, 1854), Scirpophaga incertulas (Walker, 1863). The diversity index of rice pest insects was categorized as moderate with a value of 2,35 and a dominance index of 0,108. This value indicates that the distribution of species is evenly distributed so that no insect species dominates in the area.

Abstract

Selada segar telah dihasilkan oleh Warga Kecamatan Medan Labuhan melalui kegiatan pelatihan dan pendampingan dari pemanfaatan hasil pengembangan media tanam hidroponik untuk mendukung ketahanan pangan warga. Kegiatan Pengabdian kepada Masyarakat (PKM) berbasis program studi menghasilkan pengembangan media tanam hidroponik yang terdiri dari dua model yaitu media tanam hidroponik dengan Sistem Wick dan Sistem Nutrient Film Technique (NFT). Sistem wick menghasilkan kapasitas produksi Selada untuk skala rumahan dan pemberian nutrisinya bersifat praktis sedangkan sistem NFT menghasilkan produksi Selada skala usaha dan pemberian nutrisinya diatur melalui pembacaan sensor nilai konduktivitas larutan. Kegiatan pengembangan media tanam hidroponik ini menggunakan pendekatan penelitian dan pengembangan sedangkan proses pemanfaatan hasilnya adalah pelatihan dan pendampingan dengan Model Participatory Action Research dari Stephen Kemmis. Capaian dari kegiatan PKM adalah warga mendapatkan pelatihan bercocok tanam hidroponik dengan memanfaatkan bahan daur ulang sehingga meningkatkan fungsi ekonomis dari pekarangan. Selain itu, pola pendampingan dari pemanfaatan media tanam hidroponik telah meningkatkan pemahaman warga tentang ketahanan pangan keluarga.   Kata kunci: media tanam hidroponik, sistem wick, sistem NFT, dan ketahanan pangan wargaFresh Lettuce has been produced by residents of Medan Labuhan Subdistrict through training and mentoring activities using the results of developing hydroponic growing media to support family food security. Community service activities based on the study program resulted in the development of hydroponic growing media which consisted of two models, namely hydroponic growing media with the wick system and the NFT system. The wick system produces Lettuce production capacity for a home scale and the provision of nutrition is practical, while the NFT system produces business-scale Lettuce production and the provision of nutrients is regulated through sensor readings of the conductivity of the solution. This hydroponic growing media development activity uses a research and development approach while the process of utilizing the results is training and mentoring with the Participatory Action Research Model from Stephen Kemmis. The achievement of this activity was that the residents received training in hydroponic farming by utilizing recycled materials to increase the economic function of the yard. In addition, the pattern of assistance from the use of hydroponic planting media has increased people's understanding of family food security. Keywords: hydroponic growing media, wick system, NFT system, and family food security

Abstract

Gastropoda ialah salah satu dari beberapa organisme perairan yang berguna untuk keberlangsungan ekosistem yakni sebagai hubungan timbal balik dengan kondisi lingkungan. Penelitian ini bertujuan untuk mengetahui kelimpahan, dominansi dan keanekaragaman gastropoda di Pantai Bunga, Kabupaten Batu Bara, Sumatera Utara. Penelitian ini dilaksanakan pada bulan Februari-Maret 2022 dengan metode pengambilan sampel dilakukan secara purposive sampling pada tiga lokasi, tiap-tiap lokasi pengamatan dengan 30 plot berukuran 5×5 m2. Hasil dari penelitian ini ditemukan 21 spesies gastropoda yang termasuk kedalam 12 famili, dimana spesies yang paling banyak ditemukan yaitu Cerithidea alata sebanyak 302 individu. Individu paling sedikit ditemukan yaitu Tonna dolium yaitu sebanyak 4 individu. Didapatkan nilai kelimpahan berkisar antara 9,56-14,0 individu/m2, indeks dominansi berkisar 0,10-0,37 dengan kategori rata-rata spesies gastropoda tidak dominan yang diperkuat dengan nilai indeks dominansi pada masing-masing stasiun mendekati nol, indeks keanekaragaman berkisar 1,27-2,33 yang tergolong ke dalam kategori sedang. Berdasarkan hasil pengukuran penelitian menunjukkan bahwa kondisi lingkungan Pantai Bunga masih tergolong seimbang serta cocok buat kehidupan gastropoda.
